Breach of contract

On 4/9 Dec 2014 I signed a contract with Telkom for the Unlimited fixed line promo for 12 months. On 31 Dec 2014 Telkom without my permission or informing me cancelled the promo. They reversed my payment for the promo. I without knowing about the cancellation used my phone to fixed line and mobile phones. I received a bill of R 1566.25 for calls I made (far above the billing of the promo). I want my subscription to be reactivated for the Unlimited fixed line promo. I want the current billing reversed to take all calls made according to the Unlimited fixed line promo contract. Tel no ***. <br> I also want to complain about the help I received from Telkom. I Phoned 10210 waiting for more than 3 hours and 30 minutes Talking to 5 people. Every time I am just being referred without the person helping to solved my problem.
